I was curious if this is a leaked version and not the final version by waninkoko? I have tested it and it is working fine, even my hard drive seems to work better (No more lock ups when ripping games and no more skipping in guitar hero).

I can confirm that my USB mic still doesn't work unless i run rock band 2 or rock band ACDC track pack from the Rock Band Channel Located Here. and it only works for me by attempting to use it, after it gives u the message that no mic is detected, unplug it then plug it back in.

Guitar Hero games the pic wont work at all.

DLC still does not work correctly but again that is because the game is running on the incorrect IOS the Rock Band Channel fixes this problem.

Has anyone else tested it, since there are no release notes theres no way to tell yet exactly what was changed.

People seem to like leaking waninkokos stuff - seriously guys , wait until he officially releases this - he deserves the respect for keeping at things even though a whole community pretty much jumped on the original release - ill be waiting for official stuff as well
